However, in order to match the \(D^0\bar{D}^{*0}/\bar{D}^0D^{*0}\) 
non-relativistic effective field theory near threshold (the minimal charm meson model) [1]},
one needs \(\lambda _2=-2\lambda _1\) .
Hence, under this condition the \(T_{D\bar{D}^*}\)  gets the simplified form:

\(T_{D\bar{D}^*}\, =\, \lambda _2 \, \vec{u}_X \, \vec{u}_X^{\, T}\, .\)
